Demo reels are never done. I constantly add to it, edit it, delete some clips, move some around, and generally toy with it between other projects until - at some point - you have to tell yourself "Good enough" and release it into the wild, then hope for the best.
So here it is, the best I have (at the moment) of modeling, animation, editing and video production.
I work with Adobe's full suite of products, particularly After Effects. I create 3D with Cinema 4D.
